D in upper level science course

Hello pre-vets, I have a question regarding vet school for one of my friends... She is in the 2017 application cycle and currently has 3 interviews scheduled in January, and she recently got a D in a upper level science course, neuroanatomy. Before this semester she had a 3.7, and she got a 3.0 this semester. How will this effect her chances for vet school, and do you think it will be brought up in interview? She is freaking out, any advice is appreciated. Thank you.
